APPARATUS FOR CARBURETING AIR.

Application filed March 14, 1883. (No model.) Patented in FranceSeptember 9, i882, No. 150,975; in Belgium September 23, 1882.No.59,096; in Italy September 30, 1852, No. 14,634; in England January27,1883, No. 461, and in Spain July 5, 1883, No. 3,118.

To all whom, it may concern:

Be it known that I, JULEs BLONDEL, Fils. (Junior,) of Neuville Vitasse,Department of Pas-de-Oalais, in the Republic of France, have inventedcertain new and useful Improvements in Apparatus for Garbureting Air;and I do'hereby declare that the following is a full and exactdescription thereof.

The object of this invention is to produce carbureted air for heatingand lighting purposes, as well as for the production of motive power.The apparatus which I have devised for this purpose is of simpleconstruction and permits the manufacture of gas in a substantiallyautomatic manner. It may be 0011- structed with greatly-varyingcapacity, and is on that account particularly adapted for use in countryplaces, and generally in situations where coalgas cannot beadvantageously manufactured on.a large scale. I'believe, however, thateven in large cities the invention may be worked with great economy.

The accompanying drawings form a part of this specification, andrepresent what I consider the best means of carrying out the invention.

Figure 1 is an elevation, partly in section, of the entire apparatus.Fig. 2 is a vertical section of the carburetor proper. Fig. 3 is ahorizontal section on the line my, Fig. 2. Fig. 4 illustrates a modifiedform of certain parts.

Similar letters of reference indicate corresponding parts in all thefigures.

A A are two capacious tanks of masonry filled with water, in which thelarge inverted vessels or bells B B are capable of moving up and down.The vessels B B are suspended on chains 1), running over sheaves bb".Their weight is counterbalanced by suitable weights, b suspended fromthe free ends of the chains b. At the tops of the bells B B are providedcocks c d and 0 (1, respectively, the cooks c a serving for admission ofair into the bells, while the cooks d (1 allow the passage of theair,when expelled from the bells'BB', through flexible tubes D D and thestationary tubes E, E and E into the carburetor F, in which the airbecomes charged with hydrocarbon, as will be hereinafter described.

pipes D, E, and'E into the carburetor F. At

any time during the descent of the bell B the cock cl of the bell B isclosed and the cock 0' is opened. Then the weight P is hooked to thecounter-weight b of the bell B. This is conveniently done by the blockand tackle M. The weight on the free end of the chain 1) of the bell Bbeing thus increased, this end will descend, and the bell Bwill thus belifted nearly out of the water, atmospheric air being allowed to rush inthrough the open cock 0. When the bell B has attained the highestposition desired, the cock 0' is closed, the cock d opened,and theweight 1? again removed, thus allowing the bell B to gradually descendand drive the air now contained therein into the carburetor F, as willbe understood. The same operation is repeated with reference to the bellB and its cocks 0 (Z after it has ar rived in its lowest position.

The carburetor F consists of an exterior shell, the interior of which isdivided by horizontal partitions F F, &c., into two or morecompartments. In Fig. 2 I have shown four such compartments.

The space in each compartment is divided by a web of woolen or othersuitable fabric, G, arranged spirally, as indicated" in Figs. 2 and 3,the lower edge of said fabric being immersed in a volatile hydrocarbonliquid con tained in the bottom of each compartment of the carburetor.The liquid passes from a reservoir, B, through a connecting-pipe, r, provided with a suitable stop-cock, into the uppermost compartment, fillingthe same up to the level of the pipe f. reached this level, it begins toflow through said pipe down into the second compartment, filling thesame to a corresponding level; thence it passes through a pipe, f, intothe third compartment, thence througha pipe, f

When the liquid has I into the fourth compartment, from whence it isallowed to escape throughacock, f, as soon as it reaches the orificeopening from said cook.

The liquid which I propose to employ in most cases is benzine of agravity of 0.680. The air which it is desired to charge with hydrocarbonpasses in the direction opposite to the liquid. It enters the carburetorthrough the pipe E in the lowermost compartment, near the center; thenceit traverses the spiral space formed by the fabric G to the periphery ofthe carburetor F; thence it travels upward through the partition F intothe next compartment, from near the periphery of which it passesspirally inward toward the center; thence it passes through the tubeinto the center of the next compartment, from whence it travels outwardagain toward the periphery, and up again through the annular space 9provided around the partition F, and inward againtoward the center ofthe first compartment, from whence it escapes through the pipe 9 eitherinto a suitable reservoir or directly into the pipes, which direct it tothe place where it is to be consumed. The fabric G has its lower edgeimmersed in the benzine or other hydrocarbon liquid, and is constantlykept wet by its capillary attraction, and the air, passing in contactwith the extended surface of the fabric G, takes up a large quantity ofthe volatile liquid in a gaseous form.

Fig. 4' shows a modified arrangement for forcing the air into thecarburetor. In this form I employ a wheel having four or other suitablenumber of partitions or buckets, H H, &c., which are open both at theperiphery and near the center. The casing surrounding such wheel ispartially filled with water, and on revolving the wheel in the directionof the arrow the .air caught in each bucket is driven out on such bucketbeing immersed in the water through the opening near the center, andescapes through a passage, 71, as indicated.
